tpecication of Letters Patent.

Patented erigir, Siti,

'Application filed January 28, 1916.` Serial lilo. 742,"1'37 To all whom t may concern:

Be it known -that l, Mnnnni'rri Lni'ioii, a citizen of the United States, lresiding at Poughkeepsie, county of Dutchess, and ti'tate .of 1New York, have invented a new and useful Improvement in Disk-VVashers, of which `the following is a full, clear, and enact description, reference being had to the accom- 'panying drawings, whiclrform a part of disks may be thoroughly washed in hot water without bringing the operators hands in contact with eitherthe water or the disks. A preferred embodiment ot the invention is shown in the accompanying drawings, in

which disk holder.

Figure l is a vertical sectional view of the disk washer and disk holders.

Fig. 2 is a top view of the disk holder and disks.

My invention is so designed to operate in connection with a disk remover and replacer of any type, one example of which is shown in the Berrigan Patent' No. 663,114, dated Deens, 1900, which comprisesa disk holder adapted to register with the' disk supporting or retainingdevice in the separator bowl, whereby the disks may be slippedfrom the supporting device .in the separator on to the lnl the drawings the disk holder is shown as comprising three rods fr adapted to entend respectively through three recesses .b extending outwardly from the central hole in each disk c. IThe rings;n Z, fastened between the rods c near their upper ends, is provided with an extension which passes between two of the ribs on the tubularishaft of a separator, insuring the holderV being always placed in thesaine position in the transferring operation. This ringv also serves as a handle during the washing open ation.

d isa cylinder having an open bottom and a water inlet comprising a series of holes c in a circle near the top. 7c is a container inside of' which the cylinder ol is `fastened. The cylinder is shownas extending substantially above the holes e to `give more water space. f is a-piston attached to the end4 et the disk holder a and having openings g covered by a valve 71, which opens to allow water to pass downward but closes to pre-y vent its passing upward. in openiiiifg z' under the cylinder d and a passa ge j between the cylinder d', and the container ,7c allows water to pass from the inside oi the cylinder, below the piston, to the openings c.

'llhe operation Ais as follows: Alfter using the separator the disks are transferred to the disk holder having, as described, the piston f. rlllie washer is lilled to above the openings c with warin water having,- soap powder dissolved in it. The disk holder a, and with it the piston f and the disks c, are then forced downward in the cylinder. This torces the water to pass upward through the passage j, jet out -trom the holes e with considerable force and pass rapidly between the disks and upward throiigli the central holes of the disks. iks the piston` and disks pass downward each disklin i i' turn receives the full torce ot the jets;

WWhen the piston is raised vthe water flows through the openings g 'to the space under the piston which acts as a receiver -l'or the drainage from the disks, and is ready l'or another passage throughthe passage -7' and openings c. The piston thus operates a pump to circulate the water through the passages t' and j, the orifices c and the disks. :tew strokes will clear the disks o'l all milk, cream and dirt. The dirty water is then emptied out and the washer t led with very hot clear Tater. A few strokes serve to thoroughly rinse the disks, which may then be shaken out loosely so as to till the entire length of the hol der and hung' up in a warro'rplace to dry.

Whatl claim as new and desire to ses cure by Letters Patent is:

il. lin a disk washer, in combination, means aiiording a rino; et jet orifices, a pump adapted to Vforcibly discharge the water troin such orifices, a movable disk holder Itlttt nected with the holder and operable therewith as the holder is moved to carry the disks successively past the water inlet, to force water through the inlet and between the disks.

3. In a disk washer, the combination of a vessel adapted to contain water and provided with e ring of jet orifices located Within the vessel substantially above itsV bottom and substantially below its top, a car rier on which the disks are adapted to be strung one above another, said carrier being movable up and down to carry the disks through the ring, a receiver fordrainage from the disks, means aording a water passage from the receiver to the jet orifices, and a pump operatively connected with the carrier adapted to circulate water through the water passage and discharge it through the jet orifices as the disks pass through the ring.

in a disk Washer, the combination of a cylinder having` a lower discharge end, a piston leciprocalole therein, a disk carrier attached to the piston and adapted to support the disks above the piston, the cylinder having a ring of jet orifices which said disks are adapted to pass as they, with the piston, are forced downward in the cylinder, and

means atlording a passage from the dis charge end of the cylinder to said jet oriices, to cause water to he ioreed therethrough coincidently with the movement past the orifices of the outer edges ot the disks.

5. In n disk washer, the combination with a disk carrier adapted to receive the disks and hold them while being washed :1nd n piston attached to the disk carrier, of :i cylinder with an open hottom and having :i ring of jet oriliees, means ali'ording :l passage i'rom the open bottom ot the cylinder to the ring of jet oritices, said piston adapb ed to reciprocate in the cylinder und toi-ee water through the jets while the attached disk carrier 'carries the disks through thc ring.

In testimony of which invention. l have hereunto set my hand, at Poughketmsie, on this 21st day oi January, 1016.
